摘要： A scheduling apparatus for a base transceiver system (BTS), determines a point of data transmission to mobile stations (MSs). The BTS includes buffers for storing data to be transmitted to the MSs. A scheduler determines a priority of each of the MSs taking into account a data rate determined depending on a channel condition between the BTS and the MSs, a required amount of transmission data, and an amount of data to be transmitted to the MSs, and determines an MS having the highest priority among the MSs, as a destination MS to which data is to be transmitted by the BTS. The scheduler increases the required amount of transmission data upon receipt of a retransmitted data packet, and decreases the required amount of transmission data after transmitting data to the MSs.

摘要： A TDM (Time Division Multiplexing)-based mobile communication system that switches a service type according to QoS (Quality of Service). The mobile communication system includes a base transceiver system (BTS) and a mobile station (MS) connected to the BTS. The BTS monitors whether a first service provided from the BTS to the MS is satisfied according to whether at least as much data as a predetermined transmission amount is transmitted to the MS. If the first service is dissatisfied, the BTS switches a service to a second service lower in QoS than the first service so that as much data as a transmission amount smaller than the predetermined transmission amount is transmitted to the MS.

摘要： A digital predistortion apparatus is provided for predistorting a nonlinear characteristic caused by a wideband power amplifier that amplifies a input signal. The digital predistortion apparatus includes a predistorter, connected to the power amplifier via a digital-to-analog converter (DAC) and a frequency up-converter, for receiving the input signal and compensating for the nonlinear characteristic using a look-up table that depends upon a change in output power of the power amplifier. The digital predistortion apparatus further includes look-up table (LUT) updating block for adaptively updating the look-up table by comparing a feedback signal output from the power amplifier, connected thereto via an analog-to-digital converter (ADC), with the input signal output from the predistorter.
